NSF Forum: Understanding Climate Change Through Long-Term Ecological Research
Scientists address climate change effects on ecosystems from grasslands to forests to open ocean
On March 2, view a webcast of the Long-Term Ecological Research symposium.
Human activities such as burning of fossil fuels and land use change have increased atmospheric carbon dioxide by 40 percent since the start of the industrial revolution, researchers have found.
The result is a hotter Earth, with warmer average temperatures around the globe and a future climate system that will be more variable, and with more extreme events, says Scott Collins, a scientist at the National Science Foundation's (NSF) Sevilleta Long-Term Ecological Research (LTER) Site in N.M.
Sevilleta is one of a network of 26 such NSF LTER sites around the world.
This winter's historic snows may be but one harbinger of what lies ahead.
Regionally severe winter weather may be linked to a planet whose temperature is going up, scientists say, not down. A warmer atmosphere holds more moisture and, as large land masses like North America cool over winter months, increased snowfall results.
On Wednesday, March 2, 2011, NSF will host a symposium titled, "Understanding Climate Change: Perspectives from Long-Term Ecological Research."
The meeting is the tenth such annual NSF symposium to address topics in long-term ecological research.
Documenting the impacts of climate change on ecological systems requires long-term observations and experiments, says Nancy Huntly, NSF program director for the LTER network.
Scientists from across the NSF LTER network are using monitoring networks, experiments, and computer models to quantify and predict the ecological consequences of climate change, Huntly says.
Presentations at the symposium will address climate change effects on ocean, coastal and inland ecosystems, ecosystem carbon dynamics, water availability, and human dimensions of climate change.
Scientists from several LTER sites will discuss the potential impacts of adaptation and mitigation to climate change in forests, grasslands, coasts, deserts, and urban ecosystems.
NSF's LTER network spans the Arctic to the Antarctic to the tropics. The sites represent Earth's major ecosystems, and include grasslands, forests, tundra, urban areas, agricultural systems, freshwater lakes, coastal estuaries and salt marshes, coral reefs, coastal zones and the open sea.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
